An electricity supply structure for a piezoelectric vibrator includes a circuit board and a coil spring having one end positioned in contact with the circuit board and the other end with a portion extending toward the center of the spring and a rising contact portion which stands on the extending portion at a central portion of the coil spring. A piezoelectric vibrator is in contact with the free end of the rising contact portion of the coil spring and a positioning rod for positioning the coil spring is formed integrally with the base plate and is provided at the distal portion thereof with a groove in which the extending portion is insertable to prevent radial movement of the rising contact portion relative to the piezoelectric vibrator.
